[0002] The risk management efficiency of long-distance pipelines refers to the ability of long-distance pipeline companies to meet the requirements of risk management content, which is expressed as the ratio of the risk reduction value to the cost of handling the risk. It is an important indicator for evaluating the effectiveness of risk management. In the early days of long-distance pipeline risk management, a single indicator was often used to express the quality of risk management. Although it can well reflect the management efficiency of a single risk, for the entire long-distance pipeline company, it is necessary not only to consider the risk management effect of a single indicator, but also to know the comprehensive management effect of each part of the risk, so as to analyze risks and allocate resources from the overall perspective; provide a reliable basis for risk measures decision-making, create conditions for improving the management efficiency of risks, and have important significance for comprehensively improving the level of intelligent risk management.

[0003] At present, the risks of long-distance pipelines mainly include lines, stations, operations, management and other aspects.

[0088] Example

[0089] Taking a natural gas long-distance pipeline in the southwest region as an example, the risk control efficiency value analysis is carried out: the line between the JS valve chamber and the LY valve chamber is 12 km long, the design pressure is 10.0 MPa, and the design gas transmission volume is 60×10 8 m 3In the 2019 risk assessment results based on the Kent method, the third-party damage risk assessment score was 90 points, the corrosion risk assessment score was 77 points, the design risk score was 77 points, and the misoperation score was 81 points. This pipe section is not a high-risk section.

[0090] When calculating the line risk control efficiency value, it is necessary to first calculate the risk efficiency of each sub-item, taking the third-party damage efficiency value E of the line between the JS valve chamber and the LY valve chamber as p1 Taking calculation as an example, the calculation formula is as follows:

[0091] E p1 =aω1+bω2+…zω n

[0092] Among them, a, b, z are the risk reduction values ​​of each sub-item; ω i is the power index, generally required

[0093] Since the control efficiency value represents the ratio of the risk reduction value to the risk control cost, the risk reduction value is called the benefit-type indicator, and the risk control cost is called the cost-type indicator. p1 The calculation formula is:

[0094]

[0095] According to the third-party damage indicator system, benefit indicators include: ground activity level (a), minimum coverage depth (b), geomorphic characteristics (c), public education (d), pipeline right-of-way conditions (e), and line inspection frequency (f).

[0096] Cost indicators include the sum of the cost of risk measures to deal with third-party damage to each indicator system, the cost of continuity, and the implicit cost of avoiding accidents. Among them, the total cost of managing ground activity is a1, the total cost of managing the minimum coverage depth is b1, the total cost of managing landform features is c1, the total cost of managing public education is d1, the total cost of managing pipeline right of way conditions is e1, and the total cost of managing line inspection frequency is f1.

[0097] Therefore, the calculation model of the third-party damage risk management efficiency is obtained as follows:

[0098]

[0099] The values ​​of each indicator are as follows:

[0100] Table 2 Line risk management and control benefit indicators

[0101]

[0102] Table 3 Line risk management cost indicators

[0103]

[0104] Referring to the weight distribution of third-party damage indicators in the Kent method, the weight coefficients are: ω1 = 0.25, ω2 = 0.2, ω3 = 0.1, ω4 = 0.2, ω5 = 0.1, ω6 = 0.15. Therefore, the third-party damage risk control efficiency value E is calculated according to the formula p1 =3.9. Similarly, the corrosion control efficiency value E is calculated p2 =3.3, error operation control efficiency value E p3 =5.1, design control efficiency value E p4 =6.2.

[0105] Based on the improved hierarchical analysis method and historical risk statistics, the weights are divided and the weight of third-party damage in line risk management and control is calculated. p1 =0.35, the weight of corrosion in line risk management ψ p2 =0.35, the weight of misoperation in line risk control ψ p3 =0.13, the weight of design in line risk control ψ p4 =0.17. The line risk management efficiency value E is finally calculated according to the formula in step S22 above. ps =4.23.

[0106] Finally, the risk control efficiency values ​​of lines, stations, operations, and management are aggregated item by item through the exponential method and the "AND", "OR", and "multiplication" of logic gates to obtain the overall risk control efficiency value of the long-distance pipeline company. This can quantitatively describe the risk control efficiency of the long-distance pipeline company, thereby providing a scientific reference for the risk control of the long-distance pipeline company.
